ALEX A. YENYO, F JOHNSTOWN, PENNSYLVANIA.

METAL-ROLLING- MACHINE.

Application filed November 5, 1923. Serial No. 672,819.

TO (M whom it may concem:

Be it known that I, ALEX A. YENYo, citizen of the United States, residing at Johnstown, in the county of Cambria and State ofp-Pen-nsylvanla, have invented certain new and useful- Improvements in Metal-Rolling Machines, of which the followlng 1s aspeci- This invention relates to metal rolling machines and has particular reference to machines of this kind embodying four coacting die rollers and employed for rolling bars ofmetal into desired cross sectional form's.

The primary object of the invention 1s to generally simplify and improve devices of the above .kind whereby the same may meet with all of the requirements for a successful commercial use.

A specific object of the invention is to construct a metal rolling machine of the above type so that the same will be extremely durable and simple in construction as well as efficient in operation.

Other objects will appear as the nature of the invention is better understood, and the same consists in the novel forms, combination, and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a front elevational View of a metal rolling machine constructed in accordance with the present invention.

Figure 2 is a side elevational view thereof.

Figure 8 is a top plan View of the machine frame.

Figure 4: is an elevational view of one of the horizontal rollers and its shaft.

Figure 5 is a cross sectional view showing the form of bar which will be had as a prod uct of the machine shown in Figure 1, with the peripheries of the die rollers formed as shown in said figure.

Figures 6 and 7 are views similar to Figure 5 showing other forms of bars which may be had by changing the peripheral design of the die roller.

Referring more in detail to the drawings, the present invention embodies a frame including a base plate 5 integral with which and extending upwardly from the side edges of which are side frame plates 6 that are disposed in spaced parallel relation and which have relatively large ,central and tran'sversely aligned openings 7 therein.

The upper corners of the side frame plate -6 are rigidly connected against separating strains by means of bolts 8 that extend through aligned pairs of openings 9 in said frame plate.

Formedin the lower walls of theopenings 7, are transversely aligned and extending grooves 10 forming seats in which are snugly fitted bearing blocks 11 through which the ends of the horizontal shafts 12 of the lower die roller 13 extend and in which they are journalled, the roller 13 being rigidly secured upon the shaft 12 intermediate its ends so as to assume an op erative position centrally between the side plates 6 as shown in Figure 1.

The side frame plates 6 are formed with slots let that open at the tops of said plate 6 and at the tops of the openings 7 midway between the bolts 8 and disposed within these slots 14 are bearing brasses 15 upon the upper concaved faces of which are journalled the ends of the horizontal shaft 16 of the upper die roller 17, said shaft being secured onto the brasses 15 by means of bearing caps or plates 18 having their. ends bolted as at 19 to the upper edges of the frame plate 6.

The outer projecting ends of the shafts l2 and 16 are suitably formed as at 20 to have gears keyed thereon whereby rotation of one shaft is positively imparted to the other for reversely rotating the horizontal rollers 13 and 17 in a well known manner, motion being imparted to one of the gears by any suitable means as is well known in the art.

A vertical shaft 21 is'disposed centrally of each opening 7 and has its upper end journalled in the adjacent bearing block or brass 15, while its lower end is suitably journalled in the upper portion of the adjacent lower bearing block 11. The shaft 21 has a vertical die roller 22 fixed thereon within the opening 7, and the bearing blocks or brasses 11 and 15 are suitably held against outward displacement by means of securing or cap plates 23 and 24 that are respectively bolted as at 25 and 26 against the outer surfaces of the side frame plates 6 as shown in Figure 2. For the purpose of lessening the weight of the machine, the central portion of the base plate 5 may be provided with a relatively large opening 1y contlguous relation.

as at 27 in Figure 3, and if it is desired to rigidly fasten the device to the floor or other support, suitable openings may be provided as at 28 in the corners of the base plates 5 for facilitating securing of the latter to such supports by bolts or the like.

Rigid with each end of each of the rolls 13, 17 and 22 are bevelled gears 29 that mesh with each other as shown in Figure 1, to provide a serial gearing between the four rollers for reversely rotating the vertical rollers relative to each other upon driving either of the shafts l2 and 16 as above mentioned, whereby all of the rollers will be rotated in a proper direction to cause feeding of the bar to be rolled.

In the form of the rollers shown in F igures 1, 2, and I, the same are provided with annular central ribs as at 30 upon their peripheries, which ribs are formed With convex surfaces so as to provide the opposed grooves 31 in the bar as shown in Figure 5, it being noted that the rolls are so arranged as to have their edges in substantial- This form of bar is particularly useful in concrete reinforcement work, but it is obvious that by varying the peripheral designs ofthe rollers, other shapes of bars may be had such as the guard rail shown in Figure 6, at 32, or the column shown at 33 in Figure 7.

The operation is substantially the same as that, of similar machines now extensively in use and well known in the art, the present invention having reference to specific improvement of the structure whereby durability and simplicity is obtained with cheapness of manufacture and long continued use fulness.

Minor changes may be made Without departing from the spirit and scope of the invention as claimed.

lVhat I claim as new is:

In a metal rolling machine, a side plate having an opening provided With rectangularly disposed edge wall surfaces, the diagonal dimensions of the opening being vertically and horizontally disposed with relation to the base of the plate, the plate being provided at the upper and lower corners of the openings therein with grooves, bearing members mounted in the grooves, a shaft disposed vertically across the openings and bridging the space between the said bearing members and a roll mounted upon the shaft and received within the opening and having its opposite side portions projecting beyond the side faces of the plate.

In testimony whereof I affix my signature.

ALE-X A. YENYO.
